Basically, this frame (Model # L-GZ47PST-I) is not too challenging. It takes approximately 30 minutes to assemble. You’ll need a crew of two people, possibly three and no extra tools. Most parts snap-in, and the screws are knarled-head. That means neither a screwdriver nor a wrench is necessary.

Assembly Instructions

So here are Allen Roth steel gazebo assembly instructions:

  1. Take out the crossbeams, unfold them and insert them into the slots at the top of each post.
  2. Next, you will take the corner connectors and insert them into each of the top corners where the posts meet.
  3. Then you will bolt each corner. Twist them to make sure they are secure.
  4. Next, you will secure both the short and long crossbeams by inserting the middle bar connectors.
  5. Like the previous step, insert and secure the bolts.
  6. To assemble the top, you will need to insert the long corner bars into the short corner bars.
  7. The short corner bars will then go into the corner connectors.
  8. The all long corner bars will be inserted into the top connector.
  9. Next, you will slide the long and the short middle bars into middle bar connectors.

  4. One at a time, while your crew holds up posts, secure them with the hex wrench onto the posts using the medium bolts and nuts.
  5. Now you’re ready to assemble the frame for the canopy.

So gather a 4-person crew together for the next 4 hours of assembly. Keep a 5’ ladder  on hand, but the rest of the tools (wrench, hex wrench) are included.

Assembly Instructions

Here are the necessary steps for putting this 10’ x 10’ gazebo together:

  1. First, you and each crew member will need to construct the base for the posts. This is done by securing the brackets to plate covers on the posts with the short bolts. You’ll use the hex wrench.
  2. Next, you’ll place the side panels on the basis. These are secured with short bolts using the hex wrench.
  3. After that, you’ll insert the support posts into the upper part of each base. The bottom plate can be attached as well. To secure these, you’ll need the hex wrench and more short bolts.
  4. Now, you will attach the left and right crossbars together. These require the long bolts, washers, and nuts. Both the hex and regular wrenches are utilized for tightening.
  5. Then, attach the “U” plates to the crossbars at the base of each triangle. You will use the hex wrench to secure.
  6. Afterward, you’ll need to insert the long bolts, along with nuts and washers, into the middle of the crossbars. You’ll use both types of wrenches.
  7. The next step is to connect and secure the four canopy roof staffs with the fixation. Short bolts are necessary for fastening together.
  8. The next part consists of finishing off the posts by attaching the upper moldings to the support posts.
  9. Position these posts in four corners in a square formation.
  10. Then you’ll take the crossbars and place them on top of the support posts. Medium bolts and washers will be necessary for securing these together. You’ll also need the hex wrench and remember to have the bolt holes facing toward the inside of the gazebo.
  11. Next insert the upper crossbars downward into and under the crossbars. Again, you’ll need to make sure the bolt holes are facing inward.
  12. Medium bolts, washers, and the hex wrench are necessary for this step. Then you’ll secure the tops to the crossbars with the short bolts.
  13. You will then attach the fabric cover to the top of the roof connector. The final will be screwed in until it’s fastened tightly.

Myself, I did not try it but it seems that the majority of the customers who bought it loved it. They loved how professional service was as well as the fact that the assemblers were very detailed oriented, made sure the gazebo was set up correctly and were fast to accomplish the project.

As of the complains, it seems that sometimes, the assembly may take longer than usual and thus, it may come with additional charges. Also, some assembly teams were not as good as othersDifficulties with scheduling a visit is another common complaint.

  1. I received as a gift the Allen + Roth model A106004800, ITEM 878763. I need to replace the cross bar that holds the canopy at the different heights onto a attached side pole. I had a child swing from it. anyone know where I can get one?

  2. I need the metal frame that supports the canopy. My gazebo is an Allen+Roth. Model #4134949. Where do I get the frame from?

  3. I’m looking to install a sun shelter with sliding roof panels. The one instruction video I could find showed the roof panels being inserted from the top back edge which would be against the wall of the house. This may not be possible to do on my deck as I can not assemble that far from the wall and move back later. Can the panels be inserted from the lower edge?


  5. I purchased the floor model #L-PG152PST-B from Lowes (#878763).
    Unfortunately whoever took it down didn’t save a lot of the hardware. When we pull up the parts list for this model on-line to determine what needs to be ordered we’ve noticed that the list doesn’t include the small part that’s labeled with an “R”…it’s the small bracket that holds the short corner piece to the column. I’ve searched the website until I’m brain dead and connect find this price in ANY model Allen+Roth pergola. PLEASE HELP!!!!

  6. I need the assembly instruction manual for the Allen Roth Woodgrain Pergola. Model A106004800.
    Can you please email it to me.

  7. Do you carry frame parts for Allen and Roth model TPGAZ17-002 12X10 Gazebos? We need two small connector poles (part K) and one short left crossbar (part F).

  8. I recently bought and installed the 10′ x 12′ sunshelter, with sliding roof panels. So far it has been great, but I can’t get the panels to stay open. This is a concern if I get significant snow fall. Is there a trick to this that I am missing?

  9. Hi Michelle! So the Allen+Roth GF-12S039B has been discontinued. (Booo.) I would like very much to find one, or to build a replica out of wood. You’re the manufacturer… if the unit is truly at its end-of-life, can you share the technical specifications for the sections so us weekend-warriors can take a stab at making one?
    (Feel free to remove this post and email me directly. Either way, thank you in advance for your time and attention to this inquiry.)

    • I purchased a free standing pergola gazebo from Lowe’s made by Allen+Roth. The item number is 878763. The model number is L-PG152PST-B. However, the package did not contain instructions. Can you email me a copy of the instructions.

      Thank you.

  11. I am about to purchase a wood tone gabled steel gazebo # 875051. It will be mounted on a concrete slab. Unfortunately one end is about 2” lower than the other end.

  12. I installed via Lowes the A &R 10×10 metal gazebo. Over the winter a wind storm has destroyed three of the metal panels from the top.
    I need replacement panels – but do not feel I should pay. A&R has NO customer support number or process to follow. This will be my LAST A&R – and LOWES purchase unless this is rectified. Can you assist?

  13. I recently purchased a pergola from lowes and assembled same. came up short 6 bolts JJ and thought you should know pack was wrong model PG152PST-1. Do you sell the canopy for same model and how much is it?

  14. We have had the Allen Roth beige Dome Gazebo GF-12S004B for some time now. We have to replace the canopy, which we have done before. Before replacing the canopy we need to get a replacement part that has rusted and broken off at the end. Can you tell us how we can get the following replacement part?

    Thank you

  15. Please provide corner post/column base plate footprint dimensions for Hard top Gazebo model number L-GZ1150PST-A. I plan to precast concrete piers with 4 anchor bolts embedded in each corner location to attach column base plates. Also please provide anchor bolt diameter.

  16. I am trying to plan the patio layout for Model # GF-18S112B. I need to know the center to center distance on the foundation post. I prefer to set concrete footers instead of mounting to the pavers. The Lowe’s website gives one foundation dimension in the description and a different foundation dimension in the specs. I do not believe either dimension is center to center. Can you please help or provide layout drawings? Thanks

  22. We purchased the 10 x 10 hard top Gazebo. Was wondering what the over hang measures from the outside of legs to edge of roof. We are installing in the corner of our house and existing cement porch (that is covered) and don’t want to be right up against either one.

    • Hi Tom,
      Allen+Roth does not have bigger gazebos but it is possible to find other items that have a similar design and are bigger.
      What size are you looking for?

  23. We purchased the L-GZ115oPST-A My hubby is concerned about the water run off. Is there a way to install a gutter to this unit. Or any suggestions would be greatly appreciated. Also is a 10 x 10 wood deck wide enough to accommodate this Gazebo?

    • Hi Karen,
      Sure it is possible to install rain gutters on a hardtop gazebo.
      We never did it ourselves though
      Check out this video for some tips:

      I am not so sure about the deck… The base of the gazebo is exactly 10×10 so it might be hard to secure it properly on the deck.
      Hope it helps!

  24. We purchased the 10 X 10 hard top. My hubby is worried about the water run off…uggg Would it be possible to attach a gutter to the roof edge ? Or any suggestion would be greatly appreciated Thanks Karen

  25. I have an allen + roth Steel Gazebo Model # L-GZ1150PST-A. Lost the instructions so I need to download the instructions. Where can I find the location to download the instructions.

  26. I was in lowes recently and saw this ——-allen + roth 116.14-in W x 116.14-in L x 94.3-in H Tan/Black Freestanding Pergola with Canopy.
    do you ship internationally to the united kingdom?

  27. Part J was broken when we were assembling our Allen & Roth Gazezo and we do not want Lowe’s to replace the entire gazebo when we already have it half assembled. We bought your Model# GF-18S112B, Item # 875051…12’x12′ Wood Looking Hand Paint Metal Square Semi- Gazebo. There are 4 parts marked “J” we would like all 4 replaced.

  28. Where can I get replacement parts for the allen + roth 116.14-in W x 116.14-in L x 94.3-in H Tan/Black Freestanding Pergola with Canopy. I am looking for the canopy guides. Thank You.

  29. The Pergola I purchased at Lowes does not have instructions in the box and none of the above products match what I bought. The one I purchased has a flat top with the slats on the top across running front to back. the cover is a semi-transparent mesh-type cover that slides side to side. There is no pointed roof. Can I get the instructions for assembly?
